1 Claim. 1

This invention relates to radiators and more particularly to such devices as used in relation with engines provided with a liquid cOoling system.

One of the objects of this invention is the provision of a radiator provided with certain flexible parts.

Another object of this invention is the provision of a radiator adapted to be in operative relation with an engine utilizing a liquid cooling system, and constructed so as to permit the expansion of a liquid therein which has frozen.

A further object of this invention is the provision of a radiator for accommodating the expansion and contraction of a cooling medium.

Other objects and features will more fully appear from the following description and accompanying drawings, in which: Fig. l is a rear elevational view of the radiator; Fig. 2 a sectional elevational view taken along lines 2-2 of Fig. 1, looking in the direction of the arrows, and Fig. 3 a sectional perspective.

Referring to the drawings the radiator is designated by the numeral I, and consists of a frame '2 formed by a head 3 and base 4; joined by sides 56. The head and base are respectively perforated with a plurality of apertures I and orifices 8. A plurality of tubes 9 are secured to the underside of said head respectively about each of the aperture 1 while a plurality of companion tubes I are respectively secured to the top of said base about each of the orifices 8, as clearly illustrated in Fig. 3. Each of the tubes S, depending from the head, is respectively in alignment with and spaced 2. suitable distance from the end of one of tubes I0 projecting from the base. Aligned tubes 9 and II] are respectively connected together by flexible impervious sleeve joints H, which span the intermediate spaces between the adjacent ends of the aligned companion tubes 9 and I0.

An impervious flexible top or top header I2 is secured to the head by bolts I3 and forms an upper chamber I4, while an impervious flexible bottom or bottom header I is secured to the base by bolts I6 and forms a lower chamber H. An inlet I8 is disposed in said top while an outlet I9 is secured to said bottom. A capped supply conduit 20 is located on said top for supplying a liquid to the upper chamber, while a drain 2I is located in said bottom for releasing a liquid from said radiator.

A plurality of resilient springs 22-23 are respectively imbedded in the impervious flexible material constituting the top and bottom headers.

2 Said springs are airang'ed'in spaced relation so as to more substantially maintain the headers in their normal contour, as shown in cross section on Fig. 2. My preferred 'form of flexible header is that of the bottom header I5, specifically illustrated in cross section at the lower portion of Fig. 2, wherein each of the resilient springs 23--23 is provided with an inwardly disposed recess 26. This configuration of spring 23 will allow expansion of the lower header I5 because of the inward bulge. This type of header is adapted to flex when internal pressure is applied to or released from the header, due to alternate expansion and contraction of the radiator liquid upon freezing and thawing thereof.

The device functions as follows: the radiator is connected to an internal combustion engine (not shown) provided with the usual cooling system well known in the art. The cooling medium, water for instance, is then poured into the system through conduit 20 until the normal amount is supplied. As is also well known in the art the water circulates throughout the system as follows: from the engine through inlet I8 into upper chamber I4 down through the tubes to the bottom chamber and then is returned to the engine through outlet I9 in a cooled condition. It is therefore obvious that the system is adapted to contain the cooling medium. When the temperature is lowered and causes the water to freeze the latter expands, and in order to care for such expansion the bottom I5 is constructed as to flex. For instance the expanding frozen medium will cause the angular bottom immediately to flex, it being well known that the bottom portion of the radiator is the first place to rupture upon freezing of the contained liquid. When the frozen cooling medium in the bottom header I5 melts the said header resumes its normal contour or shape.

It is therefore obvious from the foregoing that the radiator is adapted respectively to care for the expansion and contraction of a frozen and liquid medium.

In the manufacture of my improved radiator, the top header I2, the bottom header I5 and the sleeve joints II, II are preferably formed from a flexible material which is impervious to the liquid forming the cooling medium of the radiator, and Which is also obviously heat resistant to such liquid when heated to its maximum degree. One flexible material I prefer to use in my radiator, comprises a suitable rubber composition or an equivalent, and the flat resilient springs 22, 23 secured within the interiors of the headers I2,

15 for causing the flexing and reflexing of said headers are respectively imbedded therein by any well known process of vulcanization.

It is to be further understood that the impervious flexible material used in the construction of the invention is heat resistant since it must be capable of functioning with the heat liquid that comes from the engine. The fabricated material used also possesses the characteristics and qualities of rubber with respect to flexing, contracting and expanding.

Having described this invention, claimed is:

In a radiator, the combination consisting of a plurality of liquid compartments including a top header and a bottom header, a plurality of sleeved conduits respectively connecting said top and bottom headers in communicable fashion, said bottom header being flexible and impervious to a liquid and being heat resistant and provided with an angular base; a plurality of spaced resilient members embedded in and across said bottom head in transverse fashion so as to permit the what is flexing and reflexing of said bottom head when an internal force is applied to and released from said last named head; said resilient members permitting the outward and inward bending of the flexible bottom head under variable internal pressures.
